Technical field

The present invention relates to a washing machine capable of suppressing vibration and noise.

Background technique

In the past, a washing machine is generally known in which a cylindrical outer cylindrical can is supported inside a box-shaped casing, and a washing and dewatering tub as an inner tub is rotatably supported inside the outer tub (for example, refer to Patent Document 1 ).

FIG. 4 is a longitudinal cross-sectional view schematically showing an example of such a general washing machine 101.

In the internal space Sp of the casing 2, an outer tub 105 and an inner tub 106 are coaxially arranged, and a bottom plate 161 of the inner tub 106 is provided with a stirring blade 63. Further, on the lower side of the bottom plate 151 of the outer tub 105, a drive mechanism 107 capable of selectively rotating the inner tub 106 and the agitating blades 63 is provided.

A washing tub unit 104 is formed by the outer tub 105, the inner tub 106, and the driving mechanism 107, and the washing tub unit 104 is suspended and supported by the inside of the cabinet 2 via the hanger 103. The boom 103 is disposed at a predetermined angle θ, and the base end 103A side is attached to the suspension portion 25 provided near the upper end 24 of the casing 2, and the tip end 103B side is attached to the peripheral wall of the outer tub 105 via the damper mechanism 31. The lower suspended support portion 152, whereby the washing tub unit 104 is elastically supported. Thereby, it is possible to suppress the vibration caused by the rotation of the inner tub 106 and the stirring blade 63 at the time of washing or dehydration from being excessively large.

Here, the width and the depth dimension of the installation place of the washing machine 101 as described above are restricted by the waterproof board and the layout of the house in the home. That is, the installation area of the washing machine 101 cannot be made larger or more. Further, since the washing machine 101 is set to be able to wash a plurality of laundry at a time, the washing capacity is designed to be as large as possible, whereby the whole becomes long.

Further, in a manner that occupies most of the internal space Sp of the casing 2, from the vicinity of the upper end 24 to the vicinity of the bottom surface 21, there is a washing tub unit 104 which is designed to be vertically long like the casing 2. Since the washing tub unit 104 is provided with a driving mechanism 107 having a weight on the bottom plate 151 of the outer tub 105 constituting it, the center of gravity position Pc exists below the center. Therefore, the height Hc0 of the gravity center position Pc0 of the washing tub unit 104 is 30% from the setting surface F to the height Hu of the upper end 24 of the cabinet 2.

Further, in order to effectively suppress the swinging rotation of the washing tub unit 104, it is preferable to mount the hanger 103 at a position substantially the same height as the center of gravity Pc0 of the washing tub unit 104, and therefore, the above-described suspended supporting portion 53 is provided in the outer tub.

Problems to be solved by the invention

As described above, in the conventional washing machine, since the center of gravity of the washing tub unit is low, but the pitch of the fulcrum supporting the suspension is long, the swing of the washing tub unit becomes large accompanying the rotation of the inner tub and the stirring flap, so that The tendency to increase vibration and noise. Further, in the case where the washing tub unit swings and rotates, in order not to cause contact with the casing, it is necessary to establish a gap between the peripheral wall of the outer tub and the casing, which becomes a useless space, so that the washing capacity is limited.

Summary of the invention

An object of the present invention is to effectively solve such a problem, and in particular, to provide a washing machine capable of effectively suppressing vibration and noise of a washing tub unit, and capable of reducing a gap between a peripheral wall of the outer tub and the casing to reduce Useless space.

Solution to solve the problem

In order to achieve the related object, the present invention adopts the following scheme.

That is, the washing machine of the present invention includes: a casing having a box shape and having an inner space opened upward; and a washing tub unit suspended and supported by the hanging rod in the internal space, the washing tub unit having The outer tub has a bottomed quasi-cylindrical shape; the inner tub has a bottomed quasi-cylindrical shape, is coaxially disposed inside the outer tub, and is rotatably supported by the outer tub; and a driving mechanism is disposed on the a lower end of the outer tub for rotationally driving the inner tub, a base end side of the boom is mounted near an upper end of the casing, and a top end side is mounted on a lower portion of the outer tub, and a center of gravity of the washing tub unit is It is set to a position higher than the height center of the casing in the vertical direction.

Further, in the invention, it is preferable that the boom is mounted at a predetermined angle, and the tip end side is mounted on a suspended support portion provided at a lower portion of a peripheral wall of the outer tub, and the suspended support portion is set to be larger than The height of the chassis in the up and down direction is high.

Further, in the present invention, preferably, the driving mechanism selectively drives the inner tub and the agitating blade provided at the bottom of the inner tub by transmitting a rotational force of the motor, and the depth of the inner tub is set to be more than 50% of the diameter of the inner tub. Within the range of 70% or less.

Moreover, in the present invention, it is preferable that a housing portion is provided below the washing tub unit.

Further, in the invention, it is preferable that the housing portion is a drawer.

Effect of the invention

According to the invention as described above, the washing tub unit is suspended and supported by the upper end of the casing as a fulcrum by the boom, and the center of gravity is set at a position higher than the height center of the casing in the vertical direction, thereby passing the driving mechanism. The swing generated when the inner tub is rotated becomes small, so vibration and noise can be reduced. Further, since the swing rotation becomes small, correspondingly, the gap between the peripheral wall of the outer tub and the cabinet can be reduced, thereby reducing the useless space, and accordingly, by expanding the outer tub and the inner tub constituting the washing tub unit accordingly The diameter can increase the washing capacity.

Further, according to the present invention in which the suspended support portion on the distal end side on which the boom is attached is set at a position higher than the height center in the vertical direction of the casing, the size of the casing and the hanger are mounted on the casing. When the position is set to be the same as in the past, the pitch of the fulcrum that supports the washing tub unit by the hanger is shortened. Therefore, the swing of the washing tub unit can be further reduced, thereby further reducing vibration and noise. Further, since the hanger is attached at a predetermined angle and the pitch of the fulcrum is shortened, the peripheral wall of the outer tub can be positioned in the outer diameter direction as compared with the prior art, thereby reducing the useless space. Further, since the gap between the outer tub and the cabinet and the gap between the outer tub and the inner tub are reduced by the above-described reduction in vibration, the diameters of the outer tub and the inner tub can be increased, and the washing capacity can be increased.

Further, according to the present invention in which the depth of the inner tub is set to be in the range of 50% or more and 70% or less of the diameter, since the pouring of the inner tub relative to the outer tub can be reduced without impairing the washing performance of the washing machine, the outer tub can be reduced The gap between the inner tubs further increases the washing capacity and can reduce the amount of useless water (i.e., dead water) injected between the outer tub and the inner tub during washing. In addition, when the diameter is the same as the conventional one, since the inner tub becomes shallow, it is easy to take out the laundry. In addition, since the distance between the laundry and the water in the upper portion of the inner tub is relatively close to the agitating wing, the stirring force generated by the stirring blade becomes easy to be transmitted, so that the load of the motor can be reduced, thereby reducing the manufacturing cost and the energy consumption. .

Further, according to the present invention in which the accommodating portion is provided below the washing tub unit, the space under the washing tub unit can be effectively utilized, and the usability can be further improved.

In particular, the present invention in which the storage unit is a drawer can be used as a storage space for a detergent, a softener, or an appliance related to washing, and the usability can be further improved.

Referring back to Fig. 1, the outer tub 5 constituting the washing tub unit 4 is a bottomed quasi-cylindrical member having a bottom plate 51 which is a substantially circular shape in a plan view and a peripheral wall 52 which is erected from an edge portion of the bottom plate 51. In the lower portion of the peripheral wall 52, a hook-shaped suspended support portion 53 is integrally provided in a substantially uniform arrangement at four locations in a plan view. The suspended support portion 53 can be attached to the tip end 3B side of the boom 3.

The inner tub 6 is disposed as a so-called washing and dewatering tub, and has a bottomed quasi-cylindrical shape having a bottom plate 61 that is substantially circular in plan view and a peripheral wall 62 that is erected from an edge portion of the bottom plate 61. The inner tub 6 is disposed coaxially with the outer tub 5 inside the outer tub 5, and is rotatably supported by the outer tub 5 via the drive mechanism 7. A plurality of water-passing holes (not shown) are provided in the bottom plate 61 and the peripheral wall 62, and the water in the inner tub 6 can be discharged through the water-passing holes. Further, a stirring blade 63 generally called a pulsator is disposed coaxially above the bottom plate 61 of the inner tub 6.

The drive mechanism 7 includes a substrate member 71 mounted on a lower surface of the bottom plate 51 of the outer tub 5, a motor 72 mounted to the substrate member 71, and a power distribution unit 73 including a clutch. The motor 72 and the power split unit 73 are provided with a pulley 72a and a pulley 73a, respectively, and the endless belts 74 are wound around the

pulleys

72a and 73a, whereby power can be transmitted to each other.

The power distribution unit 73 includes two

output shafts

75 and 76 that are coaxially mounted, and connects the inner first output shaft 75 to the center of the agitating blade 63 and the outer second output shaft 76 to the bottom plate 61 of the inner tub 6. The power distribution unit 73 can selectively switch the output target of the driving force input from the motor 72 through the pulley 73a to the first output shaft 75 or to the first output shaft 75 and the second output shaft in accordance with an instruction from the outside. 76 sides. Therefore, the washing machine 1 can mainly rotate only the agitating blades 63 at the time of washing, and integrally rotates the inner tub 6 and the agitating blades 63 during dehydration.

The hanging rods 3 are arranged in four corners corresponding to the four corners of the casing 2. Each of the booms 3 is slightly inclined so that the distal ends 3B approach each other, and the base end 3A is suspended in the suspension portion 25 of the casing 2. Further, a damper mechanism 31 including a coil spring 31A as an elastic member is attached to the tip end 3B, and the upper end 31A of the damper mechanism 31 is suspended from the suspended support portion 53 provided in the outer tub 5. Thereby, the washing tub unit 4 including the outer tub 5 is suspended and supported by the four hanging rods 3.

Fig. 2 is a longitudinal sectional view schematically showing the washing machine 1. In the figure, the same portions as those in Fig. 1 are denoted by the same reference numerals. Hereinafter, the dimensional relationship of each portion will be described in detail with reference to FIG. 4 while referring to FIG.

First, the height Hu of the casing 2 is defined as the dimension from the installation surface F to the upper and lower directions of the upper end 24 of the casing 2. In the present embodiment, the overall size of the casing 2 is set to be substantially the same as that of the conventional conventional washing machine, and the height Hu of the casing 2 is set to be the same as that of the conventional washing machine, and is about 770 mm.

Further, the bottom plate 61 of the inner tub 6 is set at a position higher than the conventional one, and is disposed shallow from the upper end 24 of the casing 2 to the bottom plate 61.

Here, the depth Dp1 of the inner tub 6 is defined as the size from the upper end 24 of the cabinet 2 to the lowermost direction of the lowermost surface of the upper surface of the bottom plate 61 of the inner tub 6, and the diameter Di1 of the inner tub 6 is defined as the inner surface of the peripheral wall 62 of the inner tub 6. The maximum diameter at the place. In the conventional general washing machine 101 (refer to FIG. 4), in the case where the depth Dp0 and the diameter Di0 of the inner tub 106 are defined in the same manner as described above, generally, the depth Dp0 of the inner tub 106 is about 110% of the diameter Di0, which is more Longer.

On the other hand, in the washing machine 1 of the present embodiment, the depth Dp1 of the inner tub 6 is set to be about 60% of the diameter Di1, which is about half the depth of the conventional inner tub of the washing machine. Therefore, the laundry can be easily taken out of the inside of the inner tub 6. Further, since the height Hu of the casing 2 is the same as that of the conventional washing machine casing, the upper end 24 does not become too low, and it is not necessary to bend down when the laundry is taken out.

Further, since the inner tub 6 is connected to the second output shaft 76, the height from the supported bottom plate 61 to the upper end 64 also becomes low, so even in the case where the laundry is put into the extreme position of the upper end 64, the laundry is also It will be unbalanced during rotation, so that the moment acting in the direction in which the inner tub 6 is tilted is also reduced. Therefore, the relative displacement of the outer tub 5 and the inner tub 6 can be reduced, so that the gap Ci1 between the outer tub 5 and the

peripheral walls

52, 62 of the inner tub 6 can be made larger than the

peripheral walls

152, 162 of the existing washing machine outer tub 105 and inner tub 106. The gap between the Ci0 is small. Specifically, the gap Ci1 is set to be about 80% of the existing gap Ci0. Thereby, it is possible to further reduce the useless space, and it is also possible to reduce useless water, that is, dead water which enters between the outer tub 5 and the inner tub 6 at the time of washing.

Further, in the case where the stirring force generated by the stirring blade 63 at the time of washing needs to be transmitted to the upper end 64 of the inner tub 6, since the height to the upper end 64 becomes small, even if the stirring force is set small. Therefore, the capacity of the motor 72 can be set smaller than that of the conventional motor 172, and the load resistance performance of the power distribution unit 73 can be set smaller than that of the conventional power distribution unit 173, thereby making the drive mechanism 7 small. And cost reduction. In addition, it is also possible to reduce the power consumption generated by the motor 72, thereby achieving a reduction in operating cost.

Further, as described above, as the bottom plate 61 of the inner tub 6 is set at a higher position, the bottom plate 51 of the outer tub 5 and the drive mechanism 7 attached to the lower surface side thereof are also set at a higher position. Therefore, the center of gravity position Pc of the entire washing tub unit 4 is also set at a higher position.

Here, the height Hc1 of the center Pc1 of the washing tub unit 4 is defined as the dimension from the installation surface F to the vertical direction of the center of gravity Pc. In the conventional general washing machine 101 (see FIG. 4), in the case where the height Hc0 of the center of gravity Pc0 of the washing tub unit 104 is defined in the same manner as described above, in general, the height Hc0 of the center of gravity Pc0 is approximately the height of the cabinet 2. 40% of Hu.

On the other hand, in the washing machine 1 of the present embodiment, the height Hc1 of the center of gravity Pc1 of the washing tub unit 4 is larger than 50% of the height Hu of the cabinet 2. That is, when the 1/2 position of the height Hu of the casing 2 is defined as the height center Hb of the casing 2 in the vertical direction, the center of gravity Pc1 of the washing tub unit 4 is higher than the position of the height center Hb.

Therefore, in the case where the stirring blade 63 and the inner tub 6 are rotated by the drive mechanism 7, particularly in the case of the dehydrating operation in which the stirring blade 63 and the inner tub 6 are integrally rotated at a high speed, even if the washing tub unit 4 is swung and rotated In this case, since the upper end 24 of the casing 2 having the fulcrum that is suspended by the boom 3 is close to the center of gravity Pc1, the swing is reduced, and the overall vibration and noise are reduced.

Further, in the washing machine 1 of the present embodiment, the bottom plate 51 of the outer tub 5 and the center of gravity position Pc1 of the washing tub unit 4 are set to be high, and the suspended support for attaching the tip end 3B side of the boom 3 is provided. The position of the portion 53 is also higher than the position of the suspended support portion of the conventional washing machine. Specifically, the fulcrum pitch Ls1 from the suspension portion 25 for mounting the base end 3A of the boom 3 to the suspended support portion 53 for mounting the tip end 3B side is shortened to about the fulcrum pitch Ls0 of the existing washing machine. 60%. Therefore, the swing of the washing tub unit 4 can be further reduced, thereby further reducing vibration and noise.

Further, by shortening the fulcrum pitch Ls1, the length La1 of the boom 3 can also be shortened. Specifically, when the damper mechanism similar to the related art is used, the length La1 of the boom 3 becomes approximately 70% of the length La0 of the hanger 103 of the conventional washing machine. Therefore, the effect of reducing the manufacturing cost of the component and further reducing the useless space in the casing 2 can be obtained.

Further, each of the booms 3 is attached at a predetermined angle θ so that the tips 3B are close to each other. Thereby, the washing tub unit 4 applies a pulling force to the four corners via the respective booms 3, and the stability of the center position of the casing 2 in plan view can be improved. Specifically, the angle θ is set to approximately 9° as in the conventional washing machine.

When the boom 3 is inclined by a predetermined angle θ, it is necessary to set a gap Co1 between the wall surface 22 of the casing 2 and the peripheral wall 52 of the outer tub 5 in accordance with the fulcrum distance Ls1 at which the boom 3 is attached. In the present embodiment, as described above, the fulcrum pitch Ls1 is set to be as small as about 60% of the fulcrum pitch Ls0 of the conventional washing machine, and accordingly, the peripheral wall 52 of the outer tub 5 is positioned in the outer diameter direction, thereby Reducing the useless space enables the gap Co1 to be smaller than the gap Co0 of the existing washing machine. Specifically, the gap Co1 is set to about 80% of the gap Co0 of the conventional washing machine, and accordingly, the diameter of the large outer tub 5 is set.

Further, by setting the gap Ci1 between the outer tub 5 and the inner tub 6 to be smaller than the gap Ci0 of the conventional washing machine as described above, by the gap between the wall surface 22 of the cabinet 2 and the peripheral wall 52 of the outer tub 5. Co1 is set to be smaller than the gap Co0 of the conventional washing machine, and accordingly, the diameter Di0 of the inner tub 5 is increased. With In the body, by setting the diameter Di0 of the inner tub 5 to about 115% of the diameter Di0 of the inner tub 105 of the conventional washing machine, the space in the radial direction is increased, and the washing capacity can be increased. Therefore, the washing capacity is not reduced in proportion to the degree of decreasing the depth Dp1, but a sufficient washing capacity can be ensured.

Further, as described above, the washing machine 1 of the present embodiment opens the lower side of the internal space Sp to a large extent by attaching the entire washing tub unit 4 to the upper side. Therefore, it is possible to provide the drawer 8 as the accommodating portion by using this space.

Fig. 3 is a perspective view of the washing machine, showing a state in which the drawer 8 is taken out to the front side. In the lower portion of the wall surface 22 on the front side of the washing machine 1, an opening 22a formed in a rectangular shape that is long in the lateral direction is provided, and a drawer 8 is attached inside. Thus, the space below the washing tub unit 4 (refer to FIG. 2) can be effectively utilized, and the useless space can be further reduced. In addition, the drawer 8 is used as a storage space for detergents, bleaches, softeners, and washing nets necessary for washing, and it is possible to facilitate the rectification of the surrounding of the washing machine having a tendency to be disordered, and to further improve the ease of use. Sex.

It should be noted that the specific structure of each part is not limited to the above embodiment.

For example, in the above-described embodiment, the accommodating portion 8 is disposed as a drawer, but it may be disposed as a storage rack with an opening and closing door.

Further, various devices for adding additional functions may be appropriately incorporated and configured integrally to replace the arrangement of the accommodating portion 8.

Further, the size of each portion of the washing machine 1 is not limited to the above-described aspect, and can be appropriately changed.

Other configurations may be made without departing from the spirit and scope of the invention.
